Atom Structure Quiz

J.J. Thomson is credited with the discovery of the electron, a fundamental subatomic particle with a negative charge.

E. Goldstein discovered canal rays, later identified as positively charged particles, in 1886 during experiments with gas discharge tubes.

The subatomic particle discovered by E. Goldstein, later known as the proton, has a mass approximately 2000 times greater than an electron.

E. Goldstein named the positively charged rays he observed in gas discharge tubes 'canal rays,' due to their movement through the perforated cathode.

The charge of the subatomic particle discovered by E. Goldstein, the proton, is equal in magnitude but opposite in sign to that of the electron.
